CONNECTICUT, A CORPORATION OF ,CON- 1 CHAIN END.

To all whom it may concern:

' Be it known that I, Gnonon B. THOMAS, a citizen of the United States of America, and residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Chain Ends, of which the followin is a specification.

my improved chain end; Fig. 2 is a side elevation of one element of the device; Fig. 3

is a plan of the blank from which said element is formed; Fig. 4 is a detached elevation of the two elements showing the manner in which the device is attached to the chain; and Fig. 5 is a vertical section through the device assembled on the chain.

" In the form here shown in explanation of= my invention the present chain end comprises two elements, viz., a chain engaging socket A and a gripping element B sleeved thereon. The socket element has a cylindrical body slightly exceeding the diameter of the chain balls 0 and laterally apertured at 10 to permit the entrance ofthe end ball of the chain into the, interior of the socket. A slot 11 leads from the aperture 10 to the rounded end 12 of the socket, and opens into a small hole 14 of suiiicient size to permit free play to the link 13 between the two end balls of the chain. Adjacent the other end of the socket, a shoulder 15 is formed to afiord anabutment for the balPB which forms the gripping element of the device. This socket A may be conveniently rolled up from the sheet metal blank shown in- Fig. 3 and in which the bays a cotiperate to form the aperture 10 while the bumps 12 locate the shoulder 15 and serve to space apart the edges 0 to form the slot 11. The ends (2 and e are serrated to facilitate the rolling of the metal into the rounded ends of the socket, although this serration is-amnecessary. It.will be noted that the serrations at e are blunted to form the hole 14 for the link 13.

diametrically apertured at-1d and pass snugly over the socket A.

To assemble the devlce upon-a grippm element B is passed up over the ree en of the chain, the end ballof the latter inserted in the aperture 10 of the socket and run downinto the end of the Specification of Letters Patent. Patented Feb, 29, 1916.. Application filled larch 9, i i I chain, the f socket .so that the L'nifk 13 .plays1in the hole 14. The chain and socket being now alined, the ball 1s brought down on the chain and passed onto the socket until halted by the shoulder'15. The holes in the ball B are of i slightly less diameter than the socket A and.

the latter is consequently sufliciently compressed to hold the two elements frictionally together against accidental separation. Obviously the chain ball cannot escape the socket until the gripping element B sli ed oif the socket.

arious modifications of the structureshown will readily suggest themselves. I claim as my 1nvent1on:-

. 1. A device of the character described comprising a socket element adapted to receive thennid ball of a chain, in combination with an enlarged gripping element sleeved 'xupon said socket element to prevent the escape of the chain ball therefrom.

2. A device of the character describedcomprising a socket element laterally apertured to admit the end ball of a chain and, .slotted to permit its link to pass to axial a .position at one end ofsaid socket element, in combination with an enlar ed gripping element sleeved upon said soc et'and closing the lateral aperture thereof to prevent.

the escape of the chain ball therefrom in the assembled position of the parts.

comprising, a cylindrical socket element apertured to admit the end ball of achain and: :slotted to permit the chain link to pass to axial position at oneend of said socket 3. A device of the character described element, an external shoulder on the latter,

in combination with ail enlarged chain terminal element sleeved upon said socket in assembled position and abutting, against said shoulder on the socket element to prevent endwise separation of said parts when the chain is tensioned by pull upon said gripping element.

4. A device of the character described com rising a socket element 'apertured to'.

receive the endball of a. chain and slotted to permit the chain lint: to pass to axial position at one end of said socket element, in combination with an enlarged bell-like gripping element axially apertured at opposite ends to pass freely over the chain during the adjustment of the end chain hall in the socket and being sleeved upon said socket in the completely assembled condition of the device, to prevent theescape of the chain hail from the socket element.

5. In :1 chain end device of the character described, it socket element comprising a cylindrical sheetmetel body aperturecl to admit the end ball of or chain and longitudinally slotted to permit its link to pass to axial position at one end of said socket, to
